Cables by Type

SIP Cable

SIP cable, or Self-Supporting Insulated Power Cable, is a type of electrical cable designed for use in overhead power distribution systems. SIP cables are characterized by their built-in supporting elements that allow them to be installed without additional support structures. This makes them particularly useful for power distribution in areas where traditional overhead lines would be impractical or costly to install.

The self-supporting design reduces the need for additional hardware and simplifies the installation process. It also reduces installation costs by eliminating the need for extra support structures and hardware. The built-in insulation and support mechanisms provide robust protection against environmental factors and electrical faults.It is commonly used in urban and rural power distribution networks where overhead lines need to be installed efficiently and reliably and suitable for areas with limited space, complex terrain, or where traditional support structures would be difficult to install.

Construction

● Conductors: SIP cables typically use aluminum or aluminum alloy conductors for their high conductivity and light weight. The conductors may be single or multiple strands, depending on the voltage and current requirements

● Insulation: The conductors are insulated with materials such as cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR). The insulation provides protection against electrical faults, environmental conditions, and mechanical damage.

● Supporting Structure: SIP cables include a self-supporting mechanism, usually in the form of a central or peripheral support wire made of galvanized steel or aluminum alloy. This support wire enables the cable to be installed without the need for additional external supports.

Standard

GOST 31946

1. Title: Cables for Power Distribution - Aerial Bundled Cables (ABC) - Specifications

2. Scope: GOST 31946 is a Russian standard developed by the Federal Agency for Technical Regulation and Metrology (Rosstandart) that specifies the requirements for aerial bundled cables (ABC) used in power distribution systems. This standard outlines the design, construction, performance, and testing criteria for ABC cables to ensure they meet safety and operational standards in various environmental conditions.
